2. Figure 1
Forest plot of random effects of standardized mean difference (SMD) between control and treatment means for milk yield classified by enzyme type. A-EPE, C-X, C-FAE, FAE, En-X, and X represent studies involving the following enzyme types: amylase-proteolytic enzymes, cellulase-xylanase, cellulase-ferulic acid esterase, ferulic acid esterase, endoglucanase-xylanase, and xylanase, respectively. The solid diamonds represent individual studies and their weighting by the inverse of their respective variances. The horizontal lines represent the 95% confidence interval for the study. The open diamond represents the overall SMD and its width represents the associated 95% confidence interval. The solid line is the line depicting no treatment effect. The dotted line indicates the average response to exogenous fibrolytic enzyme treatment across studies as well as the heterogeneity of the studies by not passing through all the solid diamonds.

Forest plot random effects standardized mean difference (SMD) between control and treatment means for DMI. The solid diamonds represent individual studies and their weighting by the inverse of their respective variances. The horizontal lines represent the 95% confidence interval for the study. The open diamond represents the overall SMD and its width represents the associated 95% confidence interval. The solid line is the line depicting no treatment effect. The dotted line indicates the average response to exogenous fibrolytic enzyme treatment across studies as well as the heterogeneity of the studies by not passing through all the solid diamonds.

Forest plot of random effects standardized mean difference (SMD) between control and treatment means for milk protein content as affected by enzyme application method (i.e., 1 = to the concentrate, 2 = to the forage, 3 = to the TMR). The solid diamonds represent individual studies and their weighting by the inverse of their respective variances. The horizontal lines represent the 95% confidence interval for the study. The open diamond represents the overall SMD and its width represents the associated 95% confidence interval. The solid line is the line depicting no treatment effect. The dotted line indicates the average response to exogenous fibrolytic enzyme treatment across studies as well as the heterogeneity of the studies by not passing through all the solid diamonds.

Contour-line enhanced funnel plot of the standardized mean difference between treatment and control groups in all studies in the meta-analysis of effect of exogenous fibrolytic enzyme treatment on milk yield. This funnel plot represents a slight bias toward publishing favorable studies.

7. Figure A1
Forest plot of the effect of enzyme application on milk yield. The solid diamonds represent individual studies and their weighting by the inverse of their respective variances. The horizontal lines represent the 95% confidence interval for the study. The open diamond represents the 95% confidence interval for the overall estimate. The solid line represents a mean difference of zero or no effect. The dotted line indicates the mean response as well as the heterogeneity of the studies by not passing through all the solid diamonds. RMD = raw mean difference; WMD = weighted mean difference.
